无线移动自组网络MANET是由一群无线移动节点组成的网络,各节点间可以在无需集中控制或建立基础设施的情况下相互通信.为了更好地理解无线按需平面距离矢量路由协议AODV和优化链路状态路由协议OLSR在MANET中的应用,通过OPNET modeler 14.5使用不同的性能指标对两个协议的性能进行了模拟和分析.结果表明：静态情况下,OLSR的路由开销受节点数量的影响,但不受数据业务的影响,而AODV的路由开销同时受数据业务和节点数量的影响;在移动情况下,AODV和OLSR的移动速度对路由开销的影响不是很大.在节点移动速度增加的情况下,OLSR的分组投递率随之下降,而AODV的分组投递率没有变化;在端到端延迟方面,无论是在静态还是在移动的情况下,AODV总是高于OLSR.

A Mobile Ad hoc network(MANET)is a network consisting of a set of wireless mobile nodes,in which nodes can communicate with each other without centralized control or established infrastructure.For obtaining a better understanding of AODV and OLSR routing protocols,different performances are simulated and analyzed by using OPNET modeler 14.5 with the various performance metrics.The results showed that the routing overhead of OLSR is affected by the number of nodes in static case,but not data traffic.AODV is affected by both data traffic and number of nodes;in mobility case,routing overhead is not greatly affected by mobility speed in AODV and OLSR,and the PDR of OLSR is decreased as the node speed increases,while the Pdr of AODV is not changed;as to delay,AODV is always higher than OLSR in both static and mobility cases.
